LTFPRMA. 359 



LUPRiEA. 



Body elongate, parallel ; eyes extremely large ( 3 ), entire ; antennae slender, longer than the body, filiform ( <$ ), 

 and shorter in the female ; palpi thin and slender ; thorax transverse, constricted at the sides near the 

 base, surface without transverse depression, but with a broad fovea at the middle of the base ; scutellum 

 broad, trigonate ; elytra closely semipunctate-striate, their epipleurae narrow and continued to the apex ; 

 posterior femora but moderately thickened, their tibiae simple and not emarginate near the apex ; the 

 metatarsus of the hinder legs as long as the three following joints united ; claws appendiculate : posterior 

 tibiae with a distinct spine, anterior pair unarmed ; prosternum invisible between the thighs ; anterior 

 coxal cavities open. 



At first sight this curious genus has quite the appearance of a species of Galeruca, 

 especially of that of a Luperus, but the very distinctly incrassate posterior femora leave 

 no other choice but to place Luprma in the present group, where it would perhaps be 

 best placed in the 11th group of Chapuis, the Aphthoninse, on account of the open 

 anterior coxal cavities and other characters agreeing with this section. The eyes in 

 the male insect occupy nearly the entire side of the head ; the antennae in the same sex 

 are much longer than, but in the female about as long as, the body. The thorax has 

 a curious triangular depression at the base, which is joined in some specimens by an 

 anterior longitudinal groove. 



1. Luprsea longicornis. 



Below black, above dark metallic blue ; antennae longer than the body ; head and thorax impunctate ; elytra 

 distinctly and closely semipunctate-striate. 



Length 2 lines. 



Head impunctate ; frontal tubercles flattened and of subtrigonate shape ; carina indistinct ; second joint of the 

 antennae very short, the following joints elongate, slender, and of equal length, each joint furnished with 

 rather long hairs ; thorax nearly twice as broad as long, the sides rounded before the middle, narrowed 

 near the apex, with a triangular more or less distinct broad depression at the middle of the base, the 

 posterior margin in front of this depression slightly sinuate, surface impunctate ; scutellum impunctate, 

 broad, its apex more or less truncate ; elytra elongate, without any basal depression, metallic blue, closely 

 and distinctly punctured, the punctures arranged in closely approached rows and distinct to the apex, the 

 interspaces slightly transversely rugose. 



Hab. Guatemala {coll. Jacoby). 



Of this species I possess four specimens (three males and one female) from the above 

 locality. As above remarked, the eyes, as well as the antennae, are much smaller in the 

 female ; I cannot detect any other differences. Amongst the very numerous genera of 

 Halticinae I scarcely know of a form so closely resembling in shape and structural 

 characters a species of Galerucinae as the present ; the posterior femora are, however, 

 distinctly incrassate. The antennae extend either to the end of the body, or beyond it. 



2. LupraBa fdlvicollis. (Tab. XXI. fig. 11.) 



Elongate, subcylindrical ; black or piceous below ; lower part of the face, and the thorax, fulvous ; antennae and 

 legs black, the former subdilated at the intermediate joints ; thorax impunctate ; elytra obscure greenish- 

 aeneous, finely and closely rugose-punctate. 



Length 2 lines. 



Head impunctate, the vertex black, lower part fulvous ; frontal tubercles distinctly raised, slightly transverse; 

 carina robust and thickened ; labrum and palpi black ; antennae nearly two thirds the length of the body,
